Alco window pivot pins or legs

It sounds like you may be describing pivot bars. We do offer replacements for that. You may click here to go through our selection. If you should not be able to find what you need, you will need to remove the part from the window and send us over some detailed photos with measurements so that we can search for a match.

I want to add to Paul's post by noting the damage on the bottom of your sash. This isn't something we'll be able to help with. We may have a way around it depending on the style of your pivot bar, but if not then you'll have to replace the sash itself.
